Hi Dibyendu,
thanks for reporting this, I'll contact the author now to correct the link.
In future feel free to use mention feature and refer my name so I can take a look at it.
As of now we can use this very thread to report similar cases (we have also a similar thread in a private forum that is meant for moderators, and the approach seems to work very well. Let me cross-link that thread here, even if not everyone can open it, it'll be useful for me when dealing with such cases Thread to report KBAs and OSS notes with wrong links).
Cheers,
Ervin
